The invention discloses a bridge detecting vehicle working platform anti-overload control method and a bridge detecting vehicle working platform anti-overload control device. The bridge detecting vehicle working platform anti-overload control device comprises a first pin shaft sensor, a second pin shaft sensor, an anti-overload controller and a warning device, wherein the first pin shaft sensor is used for detecting stress Fa of a first detecting point a in the axial direction of an unfolding / folding oil cylinder, wherein the first detecting point a is the hinged point of the unfolding / folding oil cylinder and a lifting tower; the second pin shaft sensor is used for detecting stress Fb of a second detecting point b in the vertical direction, wherein the second detecting point b is the hinged point of a working platform and the lifting tower; the anti-overload controller is used for obtaining the current load of the platform according to Fa and Fb, and comparing the current load of the platform with the allowable load of the platform; and the warning device is used for warning according to the comparative result of the anti-overload controller. The bridge detecting vehicle working platform anti-overload control device can accurately monitor the load of the working platform, strictly prevent ultra-limit load of the working platform, avoid phenomena such as vehicle tilt, platform breakage and the like, and guarantee personal safety and device safety.
Description
technical field [0001] The invention relates to the technical field of high-altitude operation safety of construction machinery, in particular to an overload prevention control method and device for a working platform of a bridge inspection vehicle. Background technique [0002] With the development of traffic engineering, more and more bridges are being built, and regular maintenance is required, resulting in a heavy workload. The bridge inspection vehicle is a powerful auxiliary tool in the bridge maintenance process. It can provide a flexible and mobile manned platform, which is convenient for personnel to carry out all-round maintenance of the bridge. However, in the actual use process, the bridge inspection vehicle is overloaded from time to time, resulting in serious phenomena such as vehicle body tipping and platform falling. An effective device or measure is urgently needed to prevent the bridge inspection vehicle from being overloaded and ensure human-machine safety...
